ARM-FEST FOR BOOKS, &C-

SPECIFICATION forming part of Letters Patent No. 766,402, dated August 2, 1904.

Application filed September 18, 1903. Serial No. 173,710. (No model.)

To all Ir/Lom/ it nut-y (Oil/PPM.

Be it known that 1, ABRAM E. VAN Cnur,

a citizen of the United States resid i ng at. Ilighmore, 1n thceountv of i lyde and State of South Dakota, have invented a new and useful Arnr i Rest for Books, &c., of which the following is a specification.

This invention relates to hand-rests: and it is particularly adapted for the use of postmasters in filling out money-order blanks and receipts for registered letters.

One of the primary objects of the invention is to provide means for maintaining the top of the hand-rest on a plane parallel with the top of the block or book of leaves to be written upon.

A further object of the invention is to provide means for conveniently supporting a suitable backing for the leaves to be used inmanifolding.

A further object is to provide a firm support for the table of the rest.

Further objects and advantages of this invention will appear in the following descrip tion, and the novel features thereof will be particularly pointed out in the appended claims, it being understood that changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

In the drawings, Figure 1 is a perspective view of the invention, showing the application thereof. Fig. 2 is a vertical transverse sectional view through the same on the line 2 2 of Fig. 1 looking in the direction indicated by the arrow, and Fig. 3 is a vertical longitudinal sectional view.

The numeral 1 designates a base provided with a guide-rod 2 and terminally-disposed upstanding guide-flanges 3, between which is placed the block or book of leaves to be written upon.

4 designates a hinged leaf or table movable toward and away from the base- .by an adjusting device associated therewith, so that the angle of inclination of the table will be propcrl v disposed with relation to the leaves.

The adjustment of the table is effected by a threaded rotatable shaft 6, supporting an internall v-threaded sleeve 5, which is connected to the table by the oppositely-disposed links 10 and 10*, pivotally fastened to the table and adjusting member. The adjusting-rod works in bearings 7 and 8 and is provided with ahead 9, so that it can be turned and thereby move the sleeve longitudinally of the base, so as to raise and lower the hinged leaf or table. In order to add rigidity to the hinged table, the sleeve 5 is provided with oppositely-disposcd bracerods 10" and it which terminally engage the slots 1 in the respective sides of the base 1, said rods sliding freely in the slots as the adjusting-sleeve 5 is moved back and forth. At the free end of the table is a swinging leaf 11, pivoted to the guide-rod i2 and which will be employed in manifolding. This leaf can be swung under the top sheet 12 and the one immediately beneath it after a carbon-sheet has been placed between the two top sheets, and the leaf will tms provide a hard surface upon which carbon copies of the matter on the first sheet may be made. Inasmuch as the free end of the table slightly projects beneath the leaf 4, an upward movement of the free end of the table will effect an upward movement of the leaf. and adownward movement of the table will permit the leaf to gravitate on the rod. the table acting to limit its downward movement.

It will be apparent that the adjustment of the. table will be expeditious and at the same time a firm support or rest will be provided for the arm or hand.

I claim l. A device of the class set forth having a. hinged table, a movable adjusting member carried by the table, and a revoluble shaft for operating the movable member.

2. A device of the class described having a hinged table, an adjustin -sleeve, links pivoted to the table and the sleeve and a revoluble shaft for operating the sleeve to raise or lower one end of the table.

3. A device of the class described,having a hinged table, a base for the table, a movable adjusting member ca ried by the table, a revoluble shaft, for operating the movable inculher, and a transverse brace-rod carried by the adjusting device and terminally engaging the ase.

4. A device of the class described, havinge 5 slotted base, a [hinged table carried by the base, a movable adjusting member carried by the table, a shaft for operating the movable member, and a transverse brace carried by the movable member and engaging the slots IO in the base.

5. In adevice of the class described, a base,

a guide-rod on the base, a hinged table on the base, a pivoted leaf mounted on the rod and movable in one direction with the table, and

e stub-carrying means on the base.

In testimony that I claim the foregoing" as my own I have hereto afiixed my signature in the presence of two witnesses.
